EYEGLASSES.

Specification of Letters Patent.

Patented July 5, 1910.

Original application filed June 28, 1906, Serial No. 323,924. Divided and this application filed May 10,

To all whom it may concern:

Be it known that I, LEO F. AM, of Albany, in the county of Albany and State of New York, have invented certain new and useful Improvements in Eyeglasses; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of the specification, and to the reference-numerals marked thereon.

This invention relates to eyeglasses and particularly to that type in which the nose guards move substantially in a horizontal plane toward and from the nose, an object of this invention being to provide an improved manner of forming and mounting the springs which serve to proximate the nose guards.

To these and other ends the invention consists in certain improvements and combinations of parts all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

In the drawings: Figure 1 represents a top plan view of a pair of eyeglasses constructed in accordance with this invention, portions only of the lenses being shown and the guards being in proximated position. Fig. 2 is a bottom view of the connection between the bridge and one of the lenses, the guard being partially removed. Fig. 3 is a section on the line arr-a of Fig. 1 in the direction of the arrows. Fig. 4 is a bottom View of another embodiment of the connection between the bridge and a lens. Fig. 5 is a detail perspective view of the spring arm forming a continuation of the bridge, as shown in Fig. 4.

Similar reference numerals in the several figures indicate similar parts.

In an application filed by me on the 28th day of June, 1906, I have illustrated several embodiments of eyeglasses in which the bridge is provided with resilient or yielding portions serving to proximate the nose guards. The aforesaid application, in addition to containing generic claims to all of these embodiments, contains claims specific to one embodiment. This application is presented to protect specific features in other embodiments of my aforesaid application, and is, therefore, a division of the latter.

\Vith particular reference to the form shown in Figs. 1 to 3, 1 indicates the lenses Serial No. 372,844.

and 2 suitable lens-attaching members, each of which is preferably provided with a rearwardly extending horizontal arm 3. A bridge 4, made of substantially rigid material of fiat stock, is twisted slightly near opposite ends to provide horizontal portions 5 formed with vertical bearings for pivots such as screws 6, which connect the horizontal portions of the bridge with the upper face of the rearwardly-extending horizontal arms 3 near the rear ends of the latter. The bridge t at each side thereof carries forwardly projecting spring arms 7 which, near their free ends, slidingly engage the lens-attaching members 2 and serve to swing the outer ends of the lenses-toward the rear. The arms 7 are integral with the bridge and are preferably formed by doubling the ends of the flat stock edgewise in a horizontal plane so that the edge only of the metal is presented to the wearer.

To limit the swinging of the lenses 1, lugs or pins 9 project from the bridge downwardly in advance of the pivots and through curved slots 10 in the lens-attaching memhere 2, being engaged by the end walls of the slots at the ends of the swinging movements.

The nose guards 11 may be of any suitable construction, but preferably each is formed with a horizontal portion 12 which, by one of the pins 9 is pivotally secured to the under face of one of the lens-attaching members 2. Each nose guard is further formed in its horizontal portion with a slot 13 in which works a pin 14 depending from the adjacent lens-attaching member in advance of the pivot 9. It will be noted that the nose guards are pivotally connected with the bridge and with the lens-attaching members in different vertical planes, to one side or in advance of the pivots of the lens attaching members on the bridge thereby causing the movement of the lens to be increased or amplified in the nose guards.

In the embodiment shown in Figs. 4 and 5, the parts are constructed in substantially the same manner, except that the yielding or resilient extensions or arms 7 of the bridge P are bent widthwise of the stock to provide one or more convolutions making a preferably helical loop or coil 7 arranged in a plane in the rear of the lenses and having its axis substantially horizontal and parallel to the plane of the lenses.

It will be noted that in all the present embodiments, the lenses are mounted to swing in a substantially horizontal plane to proximate the nose guards and that the lenses are held in their normal position by springs forming portions of the bridge and slidingly engaging with swinging portions of the mounting, in this instance, the lens-attaching members but of course the bridge with its spring portions may be embodied in eyeglasses of other types than those in which the lenses move.

In this application I do not claim broadly the mounting of the lens attaching members to swing in a substantially horizontal plane on the bridge in combination with swingingly mounted nose guards turning about axes different from or unalined with the axes of the lens attaching members, as this feature is claimed broadly in my application No. 323,924, of which this application is a division.

I claim as my invention:

1. In an eyeglass mounting, the combination with a bridge, and a lens-attaching member mounted to swing substantially in a horizontal plane relatively to the bridge, of a spring arm extending from one of said parts and slidingly engaging the other to hold the lens-attaching members in normal position and a nose guard moved with the lens-attaching member.

2. In eyeglasses, the combination with a bridge, a pair of lenses, and lens-attaching members pivoted to the bridge to permit the lenses to swing in a substantially horizontal plane, of springs forming portions of the bridge beyond said pivots and slidingly engaging the lens-attaching members to hold the lenses in normal position.

' 3. In an eyeglass mounting, the combination of a bridge having integral spring arms extending therefrom, and lensattaching members mounted to swing relatively to the bridge and slidingly engaged by the arms so as to be retained in normal positions.

4. In an eyeglass mounting, the combination with a lens-attaching member and a nose guard, of a bridge connected with the lens-attaching member to permit a turning movement of the latter substantially in a horizontal plane for operating the nose guard and formed with an integral spring arm having sliding engagement with the lens-attaching member to position the nose guard.

5. In eyeglasses, the combination with a pair of lenses, and lens-attaching members therefor, of a bridge to which the lens-attaching members are connected so as to swing in a substantially horizontal plane, said bridge being provided with integral spring arms slidingly engaging the lensattaching members.
